Oh and I might add that all barrier ninjas are bugged. First of all. Even without the skill book the barrier stays even after using mystery (gaara, sasuke, anko etc.) and the worst of all is its bugged cooldown. If you use your barrier the last round it stays, you have to be able to reactivate it the next. Instead it gives you 3 rounds cooldown, So basically you c*e your mystery once every 6 rounds. And it has been like that since adding some skill books to the game. It is a MUST FIX! Bugs are number 1 priority! Always. Bugs are only acceptable first week after adding new patch. Some of these bugs are here for months. Why hasn't they been fixed please? :)
